Attenuation of OCT signal intensity was small in enamel. The findings may contribute to a better understanding of the interactions of light with the dental tissue.Clinical significanPrecise records of refractive indices and OCT signal patterns may be important for clinical diagnosis of caries and measurement of structural depth for operative purposes using this technology. Effects of dentin structural orientation on refractive index and scattering pattern must be considered when observing human teeth by OCT cross-sectional imaging.” (Source: Journal of Dentistry) Journal of Dentistry journals http://www.medworm.com/rss/comments.php?id=5667228 Wed, 08 Feb 2012 02:56:01 +0100 5667228 http://www.medworm.com/index.php?rid=5659801&cid=s_38503_11_f&fid=38503&url=http%3A%2F%2Fwww.sciencedirect.com%2Fscience%3F_ob%3DGatewayURL%26_origin%3DIRSSCONTENT%26_method%3DcitationSearch%26_piikey%3DS0300571212000206%26_version%3D1%26md5%3D6eaaf3348a2a952743ee21104598a9ee ConclusionsBleaching decreases the OP of the specimens (p > 0.001).

Using light-curing denture base materials requires the application of appropriate conditioning liquids to obtain acceptable bond strength. The use of MMA affects bond strength to light-curing denture base materials.Clinical Significance The pre-treament of denture teeth is critical regarding their bond-strength to denture base materials and in turn for the integrity of removable full and partial dentures. Light-curing denture base resins are more sensitive to the correct tooth pre-treatment compared to conventional MMA/PMMA materials, requiring specific conditioning liquids.

Despite the high prevalence ofH. pyloriinfection in Africa and South Asia, the incidence of gastric cancer in these areas is much lower than in other countries. Furthermore, the incidence of gastric cancer tends to decrease from north to south in East Asia. Such geographic differences in the pathology can be explained, at least in part, by the presence of different types ofH. pylorivirulence factors, especiallycagA,vacA, and the right end of thecagpathogenicity island.

It has been suggested that positive selection contributes to the evolution of virulence factors and certain functional categories in bacterial pathogens. The genusStreptococcuscontains a number of important human and agricultural pathogens. Here we assessed positive selection across 13Streptococcusspecies, and their relationship with virulence factors and functional categories. We found that known virulence genes were subject to positive selection pressure as ...

Inferences from phylogenetic analyses of nuclear SSU-rDNA and concatenated MLST sequences were compatible.Human ST3 infections were restricted to one of four identified MLO clades except where exposure to non-human primates had occurred. This suggests relatively high host specificity within ST3, that human ST3 infections are caused predominantly by human-to-human transmission, and that human strains falling into other clades are almost certainly the result of...

The interaction of this biofilm with the dental tissues may result in a caries lesion. However, lesion formation and progression can be controlled, particularly by disturbing plaque regularly with a fluoride containing toothpaste. This paradigm implies that everyone with teeth is at risk to lesion development. Treatment of caries is principally non-operative, involving plaque control, fluoride and a sensible diet. Operative dentistry repairs un-cleansable cavities and is part of plaque control. A diagnosis is a mental resting place on the way to a treatment decision. The relevant dia...

An acidic challenge prior to brushing did not negate the benefits of reduced wear from the lower RDA paste compared to the higher RDA paste. When brushing eroded dentine, the additional wear appeared independent of abrasive effect. Dentine hypersensitivity sufferers should be recommended to use a low-moderate RDA toothpaste, not to brush more than 2x/day and not immediately following an acidic challenge.

The probability of mothers aged between 35 and 39 years having a child with cleft palate was 20% higher in comparison with those between 20-29 years-old, while for those aged 40 years or more this probability was 28% higher compared to those aged between 20-29 years. Mothers aged 40 years or over were 1.56 times more likely to have a newborn with cleft lip with or without palate compared to those aged between 20-29 years. No evidence of association between early maternal and paternal age with occurrence of oral clefts was observed.

This report also highlighted that since the McGill statement in 2002, uptake by dentists of implant technology for complete denture wearers has been slow.The York statement concluded that ‘a substantial body of evidence is now available demonstrating that patients’ satisfaction and quality of life with ISOD mandibular overdentures is significantly greater than for conventional dentures.

A major public health challenge is to plan oral healthcare for this group of patients in whom avoidance of further tooth loss is of particular importance. RPDs have the potential to negatively impact on different aspects of oral health. There is clear evidence that RPDs increase plaque and gingivitis. However, RPDs have not clearly been shown to increase the risk for periodontitis. The risk for caries, particularly root caries, appears to be higher in wearers of RPDs. Regular recall is therefore essential to minimise the risk for dental caries, as well as periodontitis. There is no evidence to support a negative impact on nutritional status, though research in this area is particularly de...

Six disks were prepared for each group. APF gel was applied in a 3 mm thickness on the top surface of resin disks and left for 30 min followed by rinsing and ultrasonic washing. This procedure was repeated 4 times. TheL*a*b* values, colour difference (ΔE*ab), opacity, surface gloss and roughness of specimens before and after APF application were compared. Data were analysed ANOVA and Fisher's PLSD test withα = 0.05.ResultsFor the 3000-grit polishing groups, the order of influence of APF gel a...
